Question

If each side of a triangle is doubled, then the ratio of the area of new triangle to the given
triangle is
A) 2:1
b) 1:2
C)4:1
D)8:1​

Answer 1

If each side of a triangle is doubled, then the ratio of the area of new triangle to the given triangle is 4:1.

Answer 2

Answer:

Let a, b , c be the sides of the triangle.

Perimeter=2s = a+b+c

Semi perimeter= s=a+b+c /2

Area of the triangle =

Step-by-step explanation:

Ratio of area of the new triangle is 4:1$\sqrt{s(s - a)(s - b)(s - c)}$
